Explosion hazards arising from gas and dust
Determining the temperature class and surface temperature with the temperature table
• In the case of gas: Determine the temperature class as a function of the ambient temperature T
a
and the medium temperature T
m
.
• In the case of dust: Determine the maximum surface temperature as a function of the maximum
ambient temperature T
a
and the maximum medium temperature T
m
.
Example
• Measured maximum ambient temperature: T
ma
= 47 °C
• Measured maximum medium temperature: T
mm
= 108 °C

 20 Procedure for determining the maximum surface temperature
1. Select device.
2. In the column for the maximum ambient temperature T
a
select the temperature that is
immediately greater than or equal to the measured maximum ambient temperature T
ma
that is
present.
 T
a
= 50 °C.
The row showing the maximum medium temperature is determined.
3. Select the maximum medium temperature T
m
of this row, which is larger or equal to the
measured maximum medium temperature T
mm
.
 The column with the temperature class for gas is determined: 108 °C ≤ 120°C → T4.
4. The maximum temperature of the temperature class determined corresponds to the maximum
surface temperature for dust: T4 = 135 °C
Storage temperature –50 to +60 °C (–58 to +140 °F) (Order code for "Test, certificate", option JM)
